The ACH process with IPPAY

This diagram shows the process of ACH transaction with IPPay, when IPPay receives an ACH transaction on or before 2:30 pm CST. Click on image for larger view.
For our purpose, we always submit ACH autobills around 4 am, so our ACH autobills would get processed same day at 2:30pm. IPPay sends it to their bank at 2:30 pm CST. The transaction status changes from Pending to Phase 1.
In Phase 1, the customer’s bank has been notified. The customer can see the debit appear on his/her statement as early as this same day. Now depending on how the merchant’s ACH funding delay is set to, they will get their money. By default, this is set at 5 days. This is the time they wait for the transaction to reject or not before they pay the merchant. At this time, the status changes from Phase 1 to Phase 2.
In Phase 2, the merchant’s bank should post it to the merchant’s account the next day. Then the status will change from Phase 2 to Complete. This does not include weekends and holidays — only business days.
If an ACH transaction is received after 2:30 pm CST, it will be sent the next business day.
